Controller for water pump

Abstract

The invention discloses a controller for a water pump, and relates to the technical field of water pump controllers. The controller comprises a centerless calculation module, a local control module and a power supply system; the centerless calculation module comprises a calculation unit and a communication interface unit, and the calculation unit performs information interaction with calculation units of other controllers to obtain current running state information of the water pump; and the power supply system comprises a high-voltage battery, a low-voltage battery, a switch tube driving power supply, a power supply management unit, a high-voltage power supply, a low-voltage power supply and a switching unit. According to the controller, relevant information of accessory equipment servingthe water pump is incorporated into the control scope of the water pump, so that the water pump becomes mature integrated intelligent equipment; and meanwhile, the power supply of the low-voltage battery is independent of the power supply of the high-voltage battery, and the power supply of the low-voltage battery and the power supply of the high-voltage battery are connected with the controllerrespectively, the two sets of power supply circuits are independent of each other, and when one set of power supply circuits goes wrong, the other set of power supply circuits can be seamlessly switched, and a power supply required by work is continuously provided for the controller, so that the continuity and the safety of power supply are guaranteed.

Description

technical field [0001] The invention relates to the technical field of water pump controllers, in particular to a water pump controller. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsions, suspoemulsions and liquid metals, etc., and can also transport liquid and gas mixtures. and liquids containing suspended solids. The technical parameters of pump performance include flow rate, suction lift, lift, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into volumetric pumps, vane pumps and other types. The water pump controller is used to control the work of the water pump. [0003] On the problem of water pump group control, there are usually two solutions now. The fi...

Problems solved by technology

[0004] In order to solve the problems in the prior art, the present invention brings the related information of the auxiliary equipment serving the water pump into the control category of the water pump itself, so that the water pump becomes a mature integrated intelligent device, and reduces the installation and configuration work in the implementation process of the water supply system. The time and labor cost of project implementation are greatly reduced; at the same time, two independent power supplies of low-voltage battery and high-voltage battery are respectively connected to the controller, and the two sets of power supply circuits are independent of each other. It will seamlessly switch and continue to provide the controller with the power required for work, thus ensuring the continuity and safety of the controller's power supply
